In anatomy, arterial tree is used to refer to all arteries and/or the branching pattern of the arteries. This article regards the human arterial tree. Starting from the aorta: the following are the parts Ascending aorta It is a portion of the aorta commencing at the upper part of the base of the left ventricle, on a level with the lower border of the third costal cartilage behind the left half of the sternum. Right coronary artery posterior interventricular artery (mostly) SA nodal artery (in 60%) Right marginal artery Left coronary artery anterior interventricular septal diagonal circumflex SA nodal artery (in 40%) posterior interventricular artery (occasionally) Left marginal arteries posterolateral artery ramus intermedius (sometimes) Aortic arch brachiocephalic artery right common carotid artery right subclavian artery left common carotid artery (directly from arch of aorta on left mostly) internal carotid artery ophthalmic artery Orbital group Lacrimal artery lateral palpebral arteries zygomatic branches recurrent branch Supraorbital artery superficial branch deep branch Posterior ethmoidal artery meningeal branch nasal branches Anterior ethmoidal artery anterior meningeal artery nasal branches superior palpebral arch inferior palpebral arch Supratrochlear artery Dorsal nasal artery twig to the upper part of lacrimal sac to root of nose dorsum of the nose Ocular group Long posterior ciliary arteries Circulus arteriosus major Circulus arteriosus minor Short posterior ciliary arteries Anterior ciliary artery Central retinal artery Muscular artery anterior cerebral artery middle cerebral artery anterolateral central arteries internal striate external striate posterior communicating artery external carotid artery Arising in carotid triangle Superior thyroid artery Hyoid (infrahyoid) artery Sternocleidomastoid artery Superior laryngeal artery Cricothyroid artery Ascending pharyngeal artery Lingual artery Facial artery cervical Ascending palatine artery Tonsillar branch Submental artery superficial branch deep branch Glandular branches facial Inferior labial artery Superior labial artery Lateral nasal branch Angular artery - the terminal branch Occipital artery Posterior auricular artery Terminal branches Maxillary artery First portion Deep auricular artery Anterior tympanic artery Middle meningeal artery anterior and posterior ophthalmic artery (very rarely) superior tympanic artery vessels to semilunar ganglion superficial petrosal branch Orbital branches Temporal branches Inferior alveolar artery incisor branch mental branch lingual branch mylohyoid branch Accessory meningeal artery Second portion Masseteric artery Pterygoid branches Deep temporal arteries (anterior and posterior) Buccal artery Third portion Sphenopalatine artery, terminal branch posterior lateral nasal branches posterior septal branches Descending palatine artery greater palatine artery lesser palatine arteries Infraorbital artery orbital branches anterior superior alveolar arteries Posterior superior alveolar
